INVENTOR Patented Sept. 16, 1930 UNITED STATES CHARLES T. BRADY; OF DETROIT, MICHIGAN LAMP CONSTRUCTION Application filed February 15, 1929. Serial No; 340,053.

The present invention pertains to a novel lamp construction for household illumina tion and adapted for use in connection with floor lamps, table lamps and the like.

The usual lamps of this character include a shade constructed for attachment to the lamp socket which in turn is carried by the lamp stand or fixture. The shade is attached to the socket while there is no bulb in the lat- 'ter, and subsequently the bulb is passed into the shade through the bottom thereof and threaded into the lamp socket.

There has recently been developed a difiierent type of lamp shade having a closed bottom with a lens shutter therein, and the lamp socket is supported by the shade itself or on this bottom member rather than by the lamp stand. In order to enable the changing of shades on a given fixture without dismantling 'the shade, the present invention provides a simple means of attaching and detaching the shade with respect to the fixture by means of the device accessible through the bottom member and in a manner which does not dis turb the permanent electrical connections.

The invention is fully disclosed by way of example in the following description and in the accompanying drawing in which Figure 1 is a side elevation of a lamp shade supported on a fixture, partly in section, and Fig. 2 is a fragmentary plan view of the shade.

Reference to these views will now be had by ,use of like characters which are employed to designate corresponding parts throughout. The shade is illustrated as being made up of a wire cage or frame l which has its sides and top enclosed by suitable covering material 2 such as parchment or silk. In the bottom of the frame is inserted an'opaque bot tom member 3 having, however, a lens shutter 4 hinged thereto and equipped with a lens 5. On the bottom member is a bracket 6 carrying a lamp socket 7 positioned to support a the lens 5 which may, for example, be of such a nature as to impart a bluish or daylight character to the emanations. A conductor 9 extends from the socket 7, passing through a lamp 8 directly over the lens 5. The light issuing from the lamp is further effected by one of the ribs of the frame 1.

' The shade is to be supported on a fixture 12 which is a part of the lamp stand or bracket. The connection is made at a reduced and threaded portion 13 of the fixture.

The top structure 14 of the frame'lcarries an anchoring member in the nature of a disk 15 having a slot 16 opening through one edge thereof. The top 17 of the lamp. shade cover has an aperture 18 adjacent the slot 16' and of such size at least to receive the portion 13 of' the fixture. A conductor 19 passes axially through the fixture and is equipped at its free end with a connector element 20 adapted to be joined to a corresponding element 21 on the free end of the connector 9. A clamping or wing nut 22 adapted to thread on the portion 13 of the fixture 12 and of such size as to pass through the opening 18, is strung on the conductor 19 before themember 20 is attached thereto. In attaching the lamp shade to the fixture,

the members 20 and 21 being disconnected, the shade is raised so that the member 20 may be passed through the opening 18 and the portion 18 thenreceived in the opening. The shade is then adjusted so that the portion 13' is received in the slot 16 of theanchoring' member 15 and against'the blind end of the slot, with the upper surface of the member 15 bearing against the collar or similar 'e'nlargement 28 on the fixture 12. The nut 22 isv then brought to the portion 13 and threadedthereon against the lower surface of the member 15 until'clamped firmly against the collar 23. A washer 24 may obviously be inserted between the nut and the anchoring member if desired. The nut is reached throughthe opening in the bottom'member 3' which is exposed when the shutter 4 is pulled down on' its hinge. The lamp 8 may, of course, be removed during its adjustment. Finally, the elements 20 and 21 are connected, and the lamp .is fitted into its socket 7.

The shade is. detached from the fixture by the reverse process, namely, removing the lamp 8, uncouplingthe connector elements 20 and 21, unscrewing the nut'22 from the portion 13, bringing the fixture into the, opening 18, and finally withdrawing the lamp shade.

Although a specific embodiment of the invention has been illustrated and described, it is to be understood that various alterations in the details or" construction may be made Without departing from the scope of the invention as indicated by the appended claims.

What I claim is 1. In a lamp construction, a fixture adapted to support a shade, a shade having a slotted anchoring member adapted to receive a portion of said fixture, and a clamping device receivable on said fixture for binding the anchoring member thereon, said shade having an aaerture ad'acent the slotted anchorin member and of sufi'icient size to receive said portion of said fixture, a lamp socket supported by said shade, and conducting means extending from said socket to said fixture.

2. In a lamp construction, a fix ure adapted to support a shade, a shade having a slotted anchoring member adapted to receive a portion of said fixture, a clamping device receivable on said fixture for binding the anchoring member thereon, said shade having an aperture adjacent the slotted anchoring member and of sufficient size to receive said portion of said fixture, a lamp socket mounted Within said shade, a conductor extending therefrom, another conductor passing through said fixture into said shade, and connector elements on the ends of said conductors.

3. In a lamp construction, a fixture adapted to support a shade, a shade having a slotted anchoring member adapted to receive a portion of said fixture a clanioin device receivable on said fixture for binding the anchoring member thereon, said shade having an aperture adjacent the slotted anchoring member and of sufiicient size to receive said portion of said fixture, a bottom member in said shade, a lamp socket supported by said bottom member, a conductor extending from said socket, another conductor extending through said fixture into said shade, and connector elements on said conductors, said bottom member having an opening through which said clamping device may be reached.

4. In a lamp construction, a fixture adapted to support a lamp shade, a shade having anchoring means adapted for attachment to .saidfixture, a lens carried by said shade, a lamp socket supported by said shade and positioned to support a lamp adjacent said lens, and a conductor extending from said socket.

5. In a lamp construction, a fixture adapted to support a lamp shade, a shade having a slotted anchoring member adapted to receive said fixture, said .fixture being threaded and adapted to be received in said slot, a clampmg nut on the threaded portion of said fixture for bearing on one surfaceof said an choring member, said fixture having a collar for bearing on the other surface of said anchoring member, said shade having air aperture adjacent the slot of the anchoring member and of sufficient size to receive the threaded portion of said fixture, a lamp socket mounted Within said shade, a conductor extending therefrom, another conductor passing through said fixture into said shade, and connector elements on the ends of said conductors. v

6. In a lamp construction, a fixture adapted to support a lamp shade, a shade having anchoring means adapted for attachment to said fixture, a-lens carried by said shade, a lamp socket supported by said shade and positioned to support a lamp adjacent said lens, and a conductor extending from said socket through said fixture.

In testimony whereof I afiix my signature.
